FPCAlert.EventsBeforeRaise
Property

Gets or sets a minimal number of events that trigger the alert
before the alert's actions can be executed.

The MinutesBeforeReRaise,
EventsBeforeRaise, and MinEventsPerSecond properties set the
three thresholds that the alert service uses to signal alerts. For
each alert, the alert service stores the last time the alert was
signaled, a count of how many times the alert has been signaled per
second, and a count of the total number of times the alert has been
signaled. An alert is given and the alert invokes the actions
specific to the alert only when the three threshold requirements
for signaling an alert are met simultaneously.

The EventsBeforeRaise property sets the threshold for the
number of times the alert can be triggered before it will execute
its actions.
